If you have the rear overhead cabinet you could do a permanent solution as I did.

I cut two 1 inch dowels to size to fit on both sides of the trailer. I painted them white and ran screws from the inside of the cabinets into the dowels.
I mounted them far enough from the windows in case I ever need hanging clothes, the hanger/clothes won't hit the window. This also allowed for me to add little shelves behind the rods. I use the streetside for kitchen towels and the curbside for bath towels.

What a creative idea, Joy! I have the 2 side cabs in my scamper though. Would have preferred the long overhead, but "you gets what you gets" when you buy someone else's ideas in a used trailer. No complaints though!
